Greenwich SE10 · Lock Change & Upgrade
Lock change in Greenwich — period-home and new-build work, done same day.
Greenwich splits cleanly into two housing worlds. West and Maritime Greenwich are Georgian and Victorian period homes — solid-timber sash-fronted townhouses inside the West Greenwich, Ashburnham and East Greenwich conservation areas, many now short-lets near Cutty Sark and Greenwich Park. Greenwich Peninsula and the Millennium Village are modern new-build flats and houses on uPVC, composite and multipoint doors. That means our top three jobs here every week are: BS3621 mortice and sash-window security on the period homes, anti-snap euro-cylinder upgrades, and multipoint and composite work on the Peninsula new-builds.
Whether you have just bought a period home, taken a new-build flat off-plan, or simply want to be sure who holds a key, our fitting receipts list the lock model, the BS3621 kitemark reference, the date, and the new key count — itemised for your insurer and home records. On listed and conservation-area doors we use conservation-friendly fittings that keep the original joinery intact.
For the Georgian and Victorian timber front doors across West and Maritime Greenwich, we fit BS3621 5-lever mortice deadlocks from £180 plus a Yale 89 or Union 1332 nightlatch. For the uPVC and composite doors across Greenwich Peninsula and the Millennium Village, it's a standard euro cylinder change from £135 or an anti-snap SS312 Diamond upgrade from £200.
Short-let and holiday-let hosts near Greenwich Park and Cutty Sark use us heavily too — turnover re-keys, anti-snap upgrades, and key-safe installs for secure guest handover. Whichever you need, moving in, securing a new-build, or just an honest fixed quote for an anti-snap upgrade — book a same-day slot. From £89 fitted, fixed price first, no call-out fee.
What We Change in Greenwich
Six lock-change jobs we do day-in, day-out across SE10.

Bought a Victorian terrace in East Greenwich and wanted every external lock changed before we moved in. They came the same day, fitted a BS3621 mortice and an anti-snap cylinder, cut us a full set of keys and emailed an itemised receipt for the insurer. Tidy work, fixed price, no surprises.

We took a new-build flat at the Millennium Village and the handover keys never felt secure with so many people on site during the build. They swapped the euro cylinder for a Sold Secure anti-snap and re-keyed the communal door fob backup the same afternoon. Clear price, polite engineer, proper receipt.

Lost my keys on the way back from Greenwich Park and was locked out of our place near Vanbrugh Park. They were at the door inside 40 minutes, swapped the cylinder for an anti-snap, cut me two new keys and fitted a key safe so my partner has a spare. Fixed price, card on the day, total lifesaver.

Lock Change Greenwich — FAQs
Common questions from SE10 homeowners and residents.
Eight questions we hear week-in, week-out across Greenwich.
How much does it cost to change a lock in Greenwich?
Lock change in Greenwich starts from £89 for a basic external cylinder swap — the standard move-in re-key on SE10 front doors. Standard euro cylinder change is from £135, BS3621 5-lever mortice is from £180 (the common upgrade on the Georgian and Victorian period homes across West and Maritime Greenwich), full lock replacement from £189, anti-snap SS312 Diamond from £200. Fixed price first, no call-out fee.
Do you do same-day lock changes for Greenwich homeowners and residents?
Yes — same-day lock change is our highest-volume SE10 job. Whether you've just moved into a West Greenwich period home, want to secure a Peninsula new-build flat, or simply lost confidence in who holds a key, we change every external lock the same day. We provide an itemised fitting receipt with the lock model, key count and BS3621 kitemark reference for your insurer and home records. From £89 per door, portfolio pricing available for multi-property owners.
What lock should I fit on a period home in Greenwich?
Georgian and Victorian period front doors across West Greenwich, Maritime Greenwich and the Ashburnham conservation area take a BS3621 5-lever mortice deadlock as the main lock (kitemarked for insurance) plus a Yale 89 or Union 1332 nightlatch above. We fit BS3621 mortice from £180 and provide an itemised fitting receipt for your insurer — with conservation-friendly fittings on listed and protected doors.
How much is an anti-snap cylinder upgrade in Greenwich?
An anti-snap upgrade is from £200 fitted — SS312 Diamond or TS007 3★ cylinder (Ultion, Avocet ABS or Yale Platinum), new keys, removal of the old cylinder, and any handle adjustment. Most Peninsula new-build front doors and uPVC backdoors across SE10 still have the original builder's-spec cylinder. Lock-snapping is the no.1 forced-entry attack on UK doors — the upgrade typically pays for itself in one year of insurance excess.
Can you change locks the same day I move in?
Yes — move-in-day lock change is one of our most common Greenwich jobs. Previous owners, agents, cleaners and contractors may still hold keys. We change every external lock on the day you collect them and supply an itemised receipt for your records. Same-day across SE10, typical attendance time 60–90 minutes (depending on traffic and availability) from our SE10 base.
Do you cover Greenwich Peninsula and the Millennium Village new-builds?
Yes — Greenwich Peninsula and the Millennium Village are core SE10 coverage. New-build flats and houses run uPVC and composite doors on multipoint strips, so the usual jobs here are euro-cylinder swaps, Sold Secure anti-snap upgrades and gearbox repairs. Lost a fob key, locked out, or want a builder-spec cylinder upgraded — same-day across SE10. 24/7 phone cover on 0208 050 2017.
How long does a lock change take in Greenwich?
Most jobs take 20–45 minutes. A straight euro cylinder swap on a flat front door is under 30 minutes — the most common Greenwich job. A BS3621 mortice on a period timber door takes 45–60 minutes because the lock body sits inside the door edge and needs precise alignment. Multi-point gearbox swaps run 60–90 minutes.
Do I need a BS3621 lock for insurance in Greenwich?
Most UK home insurance policies require a BS3621 5-lever mortice deadlock on every final-exit timber door, or a multi-point locking system on uPVC/composite doors. On period timber doors the BS3621 kitemark stamped on the faceplate is the standard your insurer and Greenwich's licensing inspector will look for. We fit BS3621 mortice locks from £180 across SE10 and supply a fitting receipt with the kitemark reference.
